END-STAPLING MACHINE.

Application led September 4, 1919. Serialvo. 321,647.

Toy all whom it may con/cem.'

Be it ,known that OsoEoLA C. THOMPSON, a citizen of the United States, and resident 0f White Plains, in the county of lVestcheS- 6 ter and State of New York, has invented an Improvement in End-Stapling Machii'ics, of which the following is a specification.

This invention relates to machines for stapling box heads, box ends or the like, and l0 is intended to providecertain improvements. contributing to eliciency of operation and praoticability of construction of such ina-I chines.

Another object is to provide such a machine with means for forming and driving an improved Staple in such a manner as to increase its holding power in the work.

The in ention will be clearly understood from the following description With reference to one form of machine containing an embodiment of the invention which is shown for illustration in the accompanying drawings.

In said drawin z Fig. 1 is La si elevation of the lillustrative machine, parts thereof being broken away and other parts being shown in secytion to bet-ter illustrate the mechmiism; said figure also shows' a box, partly broken 3o away, in position to be operated upon.

Fig. 19 is a plan View of the inside end 0f a box showing the end section stapled to the cleats of side sections and showing in dotted lines the legs of the staples as deliected by the cleat material. i

Fig. 28 is an enlarged View of an irnproved staple formed b Y the machine.

The illustrative machine col'nprises, genorally, a staple forming and driving mecha.- nism for forming staples and driving them into the work; and an automatic lly 'adjustable clin'ehing mechanism to hold the box parts in position during the staple driving operation 'and ib clinch the ends of staples which may be driven through the work.

The staple forming and driving mechanism lis'carried by the frame 1. i

A staple driver 5 operates at the end of -the arm 2 to drive the staples .from the nose of the arm, which is so formed as to permit the driving of the, staples close to the box sides and 1n the corners and to gauge the sta ling point from the box sides.

he staple is formed i a holder or former 6 in the forward e of a movable carrier 7` and is driven fro said holder by the sta le drivel' 5 which is adapted to enter the ho der when it is in alinement therewith.

To supply the staple to said -holder 6, the carrier 7 is adapted to draw back the staple holder to ya cooperating staple forming 1nstrumentality'exemplified hy loop bnr 8 having a projection 9 cooperating with the holder to form the staple therein, said holder the arm 2 supported byl being the former orV die of the staple forming mechanism.

After the sta le formin operation, the carrier moves orward and positions the staple to be'e'ected by the driver apd driven into the box ead. t 4

Thus, the illustrative machine omprises a staple forming and driving mec anism in which the staple is driven`from the part in which it is formed.

An advantage, among others, in forming the staple in the part from which it is driven is that the staple may be formed and driven with longer legs than would be the case if the staple had Vto be transferred' from the former to a carrier.

In stapling box heads, the preferable practice is to drive the staples upwardly from within the box in order that the operator may more readily manipulate the box and observe the operation. The illustrative machine is designed accordingly; the stapling arm 2 affording a" support forl the box head and the stapleitdriver being arranged to drive the staple upward from the nose of said arm into the box ends and close to the sides. i,

The staple is formed in the holder 6 of the carrier 7 by the downward stroke of the loop bar 8 forcin the staple wire into the holder 6 and there )y bending the wire downward into the desired U-shape and when the carrier advances the staple to the end of the stapling arm, the driver enters the bottom of the holder and forces the staple up into the work. Thus, the staple i formed pointing up and is transferredf m forming to driving position without inv rting,,turning,v

tilting or deilecting the staple. To provide room foraction of thaw-.loop bar and associated wire feeding and cutting devices above the staple holder'butjljelow the top of the stapling arm, the carrier 7 is arranged to slide in an inclined guide 10 which brin the staple holder 6 belqwthe projection lineof the loopbar for the form-l ing operation, andcarries it flush witliftlie upper surface of the stapling arm atti-kie driving position. Thus, the staple is sugli shifted forwardly -and uplwardly wit out any tilting or turning wit its legs alW'ays pointing the same way.

The staple4 wire 4 drawn from a supplyl reel 1.1 in @the machine standard is fed'by cofacting`feed and gripping rolls 12 'and 13 and is guided -by a tube=14 which projects the staple wire m position for cutting and to be .drawn by the loop bar into'the staple former or holder 6.

The innerendof the guide tube which is carried ina spring held lever 15 is formed as a cutter16 to co-act with a stationary knife 17 to sever the portion of wire required for a staple. k

Movement of the guide tube to sever the tV the `ples approximate angle to. the sides of the cleats that the staple points orends, when driven, are de.

wire takes place at the beginning of the downward stroke of the'loop bar, and this is eii'ected by means of `a latch 18 on the loop bar engaging the end of the leverv 15 said latch being released from said lever as soon as the wire is severed by co-action of cam lugs 19 and 19", one on the latch and one fixed, whereupon the lever and guide tube are returned to normal position by means of a spring 20.

Thus the guide tube through which the staple wire passes constitutes a movable cutter and the staple wire and guide tube both move during a wire severing operation. This enables the use of a staple holderv or former which remains stationary during a staple forming operation, the projection 9 of the loop bar 8 moving into and out of the former to form the staple.

An advantage, among others, in this arrangement is that the staple which is formed in the holder orv former 6 may be quickly and easily shifted to the drivingpoint and may be driven from the holder in which it is formed thus obviating the transfer of the staple from the former to a carrier.

Referring to Figs. 3, l and 5 it will be noted that in the illustrative machine the staple wirepasses in a horizontal plane between the cutters which operate in a vertical plane at an angle of about 30 degrees to the longitudinal axis of the staple wire. Thus when the staple is .formed the points of the legs will be oppositely disposed as shown in Fig. 20 which will cause the legs to run in opposite directions when-driven linto the work as shown infFig. 19.

Referring to Figs. 3 and 7-11it will also be noted Vthat. the staple former and; loop bar are constructed and arranged .to -form the staple with `:its points vertical butin a; plane at an angle of about 45 degrees to thermedial longitudinal axis of the stapling arm, the holder 6 being formed as shown 1n Fig. 10 and the projection 9 of the loop bar being angularly disposed to cooperate therewith.

1 The wire 4 to supply the staple is fed between the projection 9 and the holder 6 in lane ofthe latter, as clearly indicated in lgs. 3 and 5. As the staple is transferred by a direct lineal movement, it is presented in drivingY position at the end of the stapling arm at the same angle, and the driver 1s shaped to operate in the holder at such an le.

An a vantage of this arrangement, among others, is that the box head may be stapled to the cleats at opposite sideswith the stay parallel and at such an ilected toward and across the lon itudinal centre line of the cleats instead o vtoward the sides thereof. Thus, as shown in Fig. 19,'

the legs of each staple become rmly em-4 -bedded in the body of the cleat instead-.of .such that in each cycle or revolution of and the box head is smily and Aheld in pla'ce.

Advantages of this arrangement, among' others, are that the machine may be utilized 'b to staple partitions or partitioning sections within the box and if desired may be o erated to form and drive the staple outsi c the box and the box.

The manner of usingthe machine will be clearly understood by those skilled in the art, and is indicated in Figs. 1 and 18 of an ordinary wirebound box with foldab y connected side-and bottom sections" provided with cooperating end`cleats and heads or ends ari-an cd inside the cleats to be stapled thereto. n performing the stapl'ing operation, the end gauge and clinch the staple within board or box head rests upon the stapling arm', as shown Fig.--1.'and the operator manipulates thc box on said arm while operating the machine successively to drive a row of staples through cach cleat: that is tosay, through the head .or end board along lines whichA cause thestaplesto pass into the cleats and in this operation, the tapered nose or terminal of the stap-le arm serves as a guide for enabligthe operator to position the work and to 1gauge the staples from the box sides.
